Isolated glide-snow avalanches, small persistent weak layer

Isolated glide-snow avalanches, small persistent weak layer

Avalanche danger above 2500 m is LOW. Weak layers inside the old snowpack can on shady slopes above approximately 2500 m still can be easily triggered in very isolated cases, particularly on wind-protected slopes at the foot of rock walls or behind abrupt discontinuties in the terrain. Avalanches can attain medium size. From smooth slopes which have not yet discharged (grass-covered, rock plates) small glide-snow avalanches can release in isolated cases.

On north-facing slopes above 2500 m the snowpack layering is unfavourable due to a sequence of melt-freeze crusts and faceted crystals in the fundament, or else depth hoar. This applies particularly to wind-protected slopes. Overall the snowpack has settled well and is quite compact. Melt-freeze crusts dominate. Snow depths are highly varied. Below 1800 m there is little snow on the ground.

On Tuesday the peaks will be partly shrouded in fog, but little precipitation is expected. In the afternoon, clouds will disperse, visibility will improve. A light to moderate westerly wind will be blowing. At 2000 m: 0 degrees; at 3000 m, -6 degrees. On Wednesday, sunshine above the fogbanks, cloudless skies, clouds will move in during the afternoon. Westerly winds at light to moderate strength, brisker in the evening. At 2000 m: +2 degrees, at 3000 m, -4 degrees.

Little change expected. We are waiting for snowfall.
